DETECTOR-BAR CLIP.

SPECIFICATION forming part of Letters Patent No. 414,862, dated November 12, 1889.

Application filcu July 3, 1888.

To all whom itmay concern:

Be it known that 1, JAMES T. HAMBAY, a citizen of the United States, residing at Wilkinsburg, in the county of Allegheny and State of Pennsylvania, have in vented or discovered a certain new and useful Improvement in and, being connected to the switch-shifting mechanism, serve to prevent any shifting of the switch-points during the movement of a car or train over them, said detector bars or rails being made of a length a little greater than the distance between the trucks of acar or the adjacent trucks of cars coupled together. v

The object of the said invention is to provide for the ready attachment of the detectorbars to the rails at any desired point, and to avoid the necessity of drilling holes through the webs of the rails.

In general terms the invention consists in the construction and combination of mechanical devices or elements, as more fully hereinafter described and claimed. I

In the accompanying drawings, forming a part of this specification, Figure 1 is a sectional elevation of a railroad-rail having my invention applied thereto. Fig. 2 is aview of the same in side elevation, and Fig. 3 is a view similar to Fig. 1 of a modification of my invention.

In the practice of my invention I form, by casting or otherwise, two blocks or jaws 1 1,

having comparatively broad flat upper faces,

so as to afford a firm bearing against the under side ofthe flange 2 of the rail, each of these blocks or jaws being provided along their outer edges with hooks 3 3, constructed to engage the edges of the flange 2, as shown in Figs. 1 and 3. The blocks being arranged on opposite sides of the rail-flange, as shown, they are held tightly in place by bolts 4, passing through the blocks, and nuts 5, screwing onto the ends of said bolts. On one of the blocks, as 1, of each pair is formed a down- SerialNo. 278,962. (No model.)

bracket is passed a pin 7 on which is mounted a movable arm 8, having a rail or bar 9 secured thereto at its upper end. The arm 8 is made of such a length that when inclined wardly-projecting bracket 6, and through said I The detector-bar rail may be arranged either outside of the main rail, as shown in Fig. 1, or inside, as shown in Fig. 3. In the latter case the bar 9 is formed of an angle-bar, one side thereof being arranged in a slit in the end of the arm 8, and the other side lying practically parallel with the tread-surface of the main rail, thus affording a broad surface with which the flange of the wheel can engage. When, however, the bar 9 is arranged outside of the main rail, in which position it will engage the tread of the wheel, only a narrow bar is employed, said bar being bolted to the ends of the arm 8. In order that the bar 9 when outside of the main rail may lie close thereto, the bracket 6 is inclined slightly out, as shown in Fig. 1, while in the construction shown in Fig. 3 the bracket is made practically vertical, the side of the angle-bar being sufflciently wide to bridge the space between the end of the arm and the rail-head.

One of the hooked blocks may have the clamping or holding bolts 4 formed integral therewith, if desired, thereby lessening the number of parts and facilitating the application of the clip to the rail-flange.

It will of course be understood that a number-e. 9., three, four, or more-of pairs of blocks are employed in connection with each detector-rail, the number being dependent upon the length of such rail.

Clips as heretofore constructed have had their bearing either upon the web of the rail or against each other below the flange of the necessary either to drill accurately located rail, or at'both these points; hence it has been holes through the web of the rail or to accnrately fit each part to the rail-flange in order to secure the clips in position, and in those forms of clip having the portions below the rail abutting against each other it has been customary to provide chipping-strips, which the Workman could reduce in fitting the clips in position. In my improved clip, however, the blocks are so constructed that the portions below the rail will not abut, and the bolt is so applied as to be in contact with or in close proximity to the rail-flange, thereby causing the portions of the blocks below the flange to have a bearing against the under surface thereof, such surface serving to properly align the blocks.

I claim herein as my invention 1. The combination, with a main rail, of hooked blocks engaging the flange of the rail, one or both of said blocks extending under said flange, but the said blocks not abutting against each other, bolts for holding said blocks in position, said bolts passing under the flange in or approximately in contact therewith, whereby the under surface of the flange effects the alignment of the blocks, and an arm pivoted to one of said blocks, substantially as set forth.

2. The combination of a main rail, a hooked block engaging one edge of the rail-flange and provided with a depending bracket, a hooked bolt having its hook engaging the opposite edge of the rail-flange, the stem of the bolt passing along in'contact with or in close proximity to the under surface of the flange, and an arm pivoted to the depending bracket, substantially as set forth.

In testimony whereof I have hereunto set my hand.

JAMES T. HAMBAY.
